2012-2017年昆仑山煤矿冰川年物质平衡数据集

本数据集针对昆仑山煤矿冰川，数据集包括平衡年、物质平衡。数据集包含6条记录。利用花杆观测法。在每年冰川消融末期，用卷尺测量不同位置的花杆在观测时的出露高度值，结合雪坑剖面，计算冰川消融量和积累量，得出每个平衡年物质净平衡，其单位为毫米水当量（mm w.e.）。在观测期间，有部分花杆倾倒或被雪覆盖，无法获取有...This dataset targets the glaciers at the Kunlun Coal Mine. It contains two core variables: balance year and mass balance, with a total of 6 records. The glacier stake observation method was adopted for field monitoring. At the end of each annual glacier ablation season, the exposed heights of stakes at different monitoring locations are measured using a tape measure during field observations. Combined with snow pit profiles, the glacier ablation and accumulation amounts are calculated to derive the net mass balance for each balance year, with the unit being millimeters water equivalent (mm w.e.). During the observation period, some stakes were either toppled over or covered by snow, making it impossible to obtain valid

背景概述

该数据集记录了2012年至2017年昆仑山煤矿冰川的年物质平衡数据，包含6条观测记录，采用花杆观测法测量冰川消融和积累量，以毫米水当量表示净物质平衡。数据在观测期间因部分花杆倾倒或积雪覆盖而存在一定局限性，主要用于反映该冰川在2012年10月至2017年10月间的物质平衡变化情况。
